To all 607mm it may concern:

Beit known that I, WILLARD L. STARLLN, of Benwood, in the county of Marshall, and in the State of West Virginia, have invented certain new and useful Improvements in Iuyere-Irons; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in the construc- 4tion and general arrangement of 'a tuyere-iron, which will be hereinafter fully set forth.

In order to enable others skilled in the art to which my invention appertaius, to make and use the saine, I will now'proceedto describe its cnstruction and operation, referring to the annexed drawings, which form a part of this specification, and in which- Figure 1 isa side view;

Figure 2 is a longitudinal vertical section;

Figure 3 is a'transverse section of the end nearest the bellows; and

Figure 4 is a transverse section of the' end nearest the fire. l v

I construct my tuyere-iron of two parts, A and B.

The 4part A is in the shape of a tapering cylinder, of suitable size, open at the larger end, but partially closed at the smaller end; that is, forming a solid end, with an opening or aperture in the centre.

Y A pipe, O, leads from this opening back through the centre of the cylinder, ending a suitable distance from the open end of the same.

lIhe cylinderA and pipe C may be cast in one piece, which is decidedly preferable to making them in several parts, and then joining them together.

The part B of the tuyere-iron forms an air-chamber, D, with an opening, E, which is connected with the bellows, and is placed over the open end of the cylinder A, and securedito the same by set-screws F F, or any other suitable means, so as to make the joint perfectly air-tight.

From the air-chamber D, one, two, or more tubes, I I, lead into the circular chamber formed between the sides of the cylinder -A and pipe C, and extend `to within a short distance from the closed end of said cyl- .inder.

The air, as it is forced into theair-chamber D from the bellows, passes through the pipes I I, thence back again to near the outside of the air-chamber D, when it enters the pipe C, and is communicated to the re.

By this arrangement, a constant current of cold air is kept, at all times, on the inside of the end near the re, cooling it, instead of the usual trouble to cool it with water.

Having thus fully described my invention,

WILLARD L. STARLIN. Witnesses:
